Any looking to get a Phlizon or Spider Farmer light as they are cheap. Understand the specs provided by the manufacturer are not true. This is my set up half of a 8x4....4x4 area took me 2 Philzon 2000w cobb and 1x Spider Farmer 2000w to obtain proper Par levels across the area. Actual watts are 450,200 total 1100 actual watts.
